Hubs and I stayed at the New York New York Hotel and received 2 complimentary buffets for breakfast or lunch with our stay.
I'm not huge on buffets in general but I'm all for free in a city like Las Vegas where a simple meal can be rather expensive. Honestly, my expectations weren't that high because of the look of the place as compare to other buffets I've visited in Las Vegas and it was free. Hotels in Las Vegas don't give away the highest quality for free, I'm just saying.
That being said, we went for lunch. It was just OK as expected. Some items were better than others but overall, the food was very cafeteria-ish, not gourmet.
The staff were excellent, I must say. Very attentive and pleasant.
